IMPROVEMENT IN ROOFING'$CAFFOLDS.

I Specification forming part of Letters Patent No. 191,333, dated May29, 1877; application filed March 24, 1877.

To all whom it may concern Be it known that I, JOSEPH A. GOODNOUGH, ofMount Pleasant, in the county of Henry and State of Iowa, have inventeda new and Improved Device for Supporting Roofing- Scaflolds, whichdevice is fully set forth in the followingspecification and accompanyingdrawing, in which Figure l is a perspective view of said device. Fig. 2is a side view, and Fig. 3 an end view, of same.

The object of my invention is to furnish an improved device by which thesupport or scaffold used by workmen to retain their position on roofsmay be easily and securely attached to the roof, and as readily detachedand removed, as desired, thereby effecting a great saving of time andlabor, and avoiding injury to roofs by driving of spikes, as nowpracticed.

In the drawing, A is the clamp for holding the scantling H. O G arehooks cast upon sides of the clamp A, for attaching to the roof. G isthe set-screw for securing thescantling in place. Bis an adjustable arm,with claws D D, and pivoted to the block A by the bolt E, and held atthe desired angle by the pin F,

as shown in Fig. 2. The whole is designed to be of cast metal.

The method of using my device is as follows: Two or more of the clampsare attached to a scantling, as shown in Fig. 2, and the arm B isadjusted to the pitch of the roof by means of the pin F; and the wholeis placed upon the roof, to which it becomes fastened by the pressure onthe scan tling.

I am aware of the patents granted to E. Parker, February 15, 1870, andJ. H. Look, Jr., July 11, 1871, and therefore disclaim the constructiontherein shown; but

What I do claim as new and useful is- An improved device for supportingrootingscafi'olds, consisting of the clamp A, having set-screw G, andprovided at its front with spurs or hooks G, in combination with the armB, having claws D D, and adjustable at different angles through themedium of the pin F, engaging with the holes in the sides of the clampA, substantially as described.
